利用语义约束实现用户个性化的服务组合算法

为了提高服务组合的质量和效率,提出了一种基于语义约束的服务组合算法.算法中,首先利用2层语义匹配算法对用户需求和服务库中的服务进行比较,利用用户约束性个性化需求对符合匹配的服务进行筛选,从而在第一时间缩小了服务组合算法执行过程中服务的搜索空间,然后对候选的服务组合组件进行用户趋向性个性化需求计算,选择其中最符合用户个性化需求的服务构成最终的服务组合.通过仿真实验证明,该算法有效提高了服务组合算法的运行效率,并且保证了用户的个性化需求得到最大满足.     

Using a discrete choice experiment to estimate spectators’ willingness to pay for professional baseball park sportscape

The physical environment of sport facilities, referred to as the sportscape, has a substantial influence on the extent to which sport fans attend sporting events and revisit the facilities. Accordingly, professional franchises make efforts to construct new stadiums with different sportscape elements, which serve as important factors that determine spectators’ levels of attendance satisfaction. With a sample of South Korean baseball fans, the authors examine which sportscape components of professional ballparks are considered most important by spectators, as well as how baseball attendees indicate their willingness to pay for particular sportscape attributes. Based on a discrete choice experimental approach, results indicate that spectators place the greatest importance on fast access to ballparks largely dependent upon the location. Results also suggest that respondents are willing to pay KR₩4102 for one more subway line. Different strategies for developing successful sportscape components are discussed.

为解决人民健身需求增长与体育场地资源不足的矛盾,以委托代理理论为理论基础对我国学校体育场地对外开放问题进行研究。认为当前我国学校体育场地对外开放面临管理主体责任划分不明晰、安全保障体系不健全、专业化服务不到位等困境,而委托代理理论可以提供解决思路。在构建学校体育场地对外开放管理模式的基础上,提出开放策略：建立完善的法律体系和有效的协调机制;加强管理,营造安全的健身环境;构建“互联网+”专业服务平台,提供优质服务。旨在为推动我国学校体育场地对外开放和更好地服务于全民健身提供依据。     

生态文明：城市休闲体育发展的必然选择

“美丽中国”战略目标的实现离不开“美丽城市”的建设。生态文明是实现美丽城市更新建设的保证者,而美丽城市的建设是落实生态文明的重要举措,两者互动发展、共同促进。城市休闲体育的蓬勃开展离不开生态文明的推动与滋养,生态文明建设是休闲体育发展的至高境界,为城市休闲体育发展提供了外在环境和内部动力。城市休闲体育通过亲近自然、绿色消费、健身怡情、协调“三生”等实际行动,起到了推动人居环境改善、拉动低碳经济增长、实现生命价值延展和促进城市休闲功能提升的作用,是生态文明建设的最佳践行手段。

Broadway productions and the value of a Tony Award

This article investigates the effect of a Tony nomination or win on the demand facing a Broadway production using a panel of weekly revenues for Broadway productions from 1996 to 2007. Our results indicate that the effect of a nomination or win is positive in the week of the announcement and gradually increases in successive weeks, presumably due to publicity and word-of-mouth. Winners experience an increase in demand as late as 1 year later when awards are publicized for the following season. Moreover, nominees that do not win the award are penalized heavily in the weeks following the Award announcements. We find that winning a Tony Award increases a production’s revenues by 12% in the week immediately following the Awards.

基于语义Web的信息门户建设

语义Web为我们提供了一个通用的框架,是现有Web的扩展.语义Web以资源描述框架(RDF)为基础,RDF以XML作为语法、URI作为命名机制,将各种不同的资源集成在一起.本文探讨了基于语义Web的图书馆门户建设,并阐明此类门户的信息结构更加合理和灵活,具有更好的扩展性、可持续性和个性化的特点.     

简析酒语词语义演化生成与修辞认知

酒语词语义系统，承载着主体最早的认知经验，是主体按照特定修辞方式凝结其语形语义，即主体以经验思维来描述对酒的认识，构建具有幻象意义的描述空间，在这个幻象空间中，隐含着主体内在共通的原型经验，成为具有多维修辞阐释空间的独特符号系统。文章采用广义修辞学相关原理简要分析酒语词语义演化生成与修辞认知。
